TAMPA, Fla. (AP) — Feeling slighted, supporters of Texas Rep. Ron Paul's presidential run are making their voices heard at a Republican convention intended to promote party harmony.

The Paul delegates booed and chanted against new party rules adopted Tuesday, which they saw as a power play by the Republican old guard.

The rules are designed to limit the ability of insurgent presidential candidates to amass delegates to future Republican conventions. They will bind delegates to the outcome of presidential primaries and caucuses, preventing a candidate like Paul from pushing up their delegate counts at state conventions.

Supporters of the new rules say voters expect the delegate count to reflect the outcome of state primaries and caucuses.
